* use a large surface ground track/fill for this circuit, otherwise the LM3524 will not work reliably!
* mount the two potentiometers through the enclosure, as shown in the picture on the start of this page (these pots are used to control the frequency and duty cycle)
* the driver is based on the LM3524 PWM chip, [...]
This power supply is designed for general purpose use. Advantages of the circuit are first the voltage can be adjusted from 0V to greater and second it does not require a double sided secondary winding transformer.
For high voltage outputs you can use L146 or alternatively if you need lower voltage outputs you can use IC [...]
The main power supply is relatively conventional - the mains supply is presented to the torroidal transformer via a fuse, a thermal cut-out and the power switch. A device that looks like a VDR is mounted on the power switch…
The secondary windings produce ±24V nominally using discrete diodes and 2 reservoir capacitors. The second pair [...]
